# The fields nw_proto, nw_tos, nw_ecn, nw_ttl in final flow seem unnecessary. Can they be avoided?
# The match on dl_dst=66:77:88:99:aa:bb in the Megaflow is a side effect of setting the dl_dst in the pushed outer
# Ethernet header. It is a consequence of using wc->masks both for tracking matched and set bits and seems hard to
# avoid except by using separate masks for both purposes.
